<FONT color="green">029</FONT>     * The major part of the methods defined in this interface deals with accessing<a name="line.29"></a>
<FONT color="green">030</FONT>     * properties of various data types. There is a generic {@code getProperty()}<a name="line.30"></a>
<FONT color="green">031</FONT>     * method, which returns the value of the queried property in its raw data<a name="line.31"></a>
<FONT color="green">032</FONT>     * type. Other getter methods try to convert this raw data type into a specific<a name="line.32"></a>
<FONT color="green">033</FONT>     * data type. If this fails, a {@code ConversionException} will be thrown.&lt;/p&gt;<a name="line.33"></a>
<FONT color="green">034</FONT>     * &lt;p&gt;For most of the property getter methods an overloaded version exists that<a name="line.34"></a>
<FONT color="green">035</FONT>     * allows to specify a default value, which will be returned if the queried<a name="line.35"></a>

<FONT color="green">040</FONT>     * of most configuration implementations provided by this package, per default<a name="line.40"></a>

<FONT color="green">045</FONT>     * exception in that case. (Note that getter methods for primitive types in<a name="line.45"></a>
<FONT color="green">046</FONT>     * {@code AbstractConfiguration} always throw an exception for missing<a name="line.46"></a>
<FONT color="green">047</FONT>     * properties because there is no way of overloading the return value.)&lt;/p&gt;<a name="line.47"></a>

<FONT color="green">050</FONT>     * can be changed. With {@code clearProperty()} a property can be removed.<a name="line.50"></a>
